Proxy multiple services through a single service.

This module forwards any number of Dagger services through a single nginx service, each on its own frontend port.

proxy
  .withService(backendService, "backend", 8080, 8080)
  .withService(frontendService, "frontend", 8081, 80)
  .service

Pass isTcp: true to proxy raw TCP (e.g. a database) instead of HTTP:

proxy.withService(postgresService, "db", 5432, 5432, isTcp: true).service
